Cardiovascular stent – Boundary Conditions

      Hello, in the 1/8 stent model everything goes according to the tutorial and i get right results. When I tried to simulate the full stent model, i constrained the 8 faces of the edges of the stent on both sides, in order to prevent the motion in the axial and tangential direction. And I also used the deformation 0.3mm as in the tutorial. Is this constrain of the 8 faces right? Because in the lesson 9 of your tutorial I'm not sure I get the hint right.nnThank you in advance, nKorina Dedousi n

      ,nI don't think any constraint is needed for the edges of the stent. You could simply define the balloon deformation. Could you try this? There might be a chance that a rigid body error shows up, in that case change the contact from frictionless to no separation.nRegards,nIshan.n
